propellers not only serve ANDREAS MARIUS VAN BEZOOYEN, OF SIOUX CITY, IOWA.

AEROPLANE.

Application filed March 29, 1918.

To all whom it may concern:

Be it known that I, ANDREAS MARIUS VAN BEZOOYEN, a subject of the Queen of H01- land, residing at Sioux City, in the county of Woodbury and State of Iowa, have invented certain new and useful Improvements in Aeroplanes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

y invention relates to a new and useful improvement in airships, and has for an object. to provide an airship wherein the as forward pro-' pelling means but may be used to drive the air ship directly upward, the machine remaining in a horizontal position.

Still another object of my invention is to so construct the air ship that it will be possible to go at a very slow speed when in the air, which is made possible by so providing the propellers that they may be set at an angle Where no propelling motion is given to the said air ship.

Still another object of my'invention is to so arrange the propellers that if desired they may be tilted at an angle to propel the machine, or on the other hand if desired they may be tilted in the opposite direction to drive the machine in a rearward direction.

Still another object of my invention is to so construct the air ship that by tilting the propellers at a certain angle on the one side and the propellers on the opposite side at an opposite angle the air ship will be guided in its flight without the use of rudders.

With these and other objects in View, my invention consists in certain new and novel constructions and combination of parts as will be hereinafter more fully described and pointed out in the claims.

Referring now to the drawings:

Figure 1 1s a side elevation of my air ship, the propellers being shown in a vertical position;

Fig. 2 is a top plan view of the same;

Fig. 3 is a sectional view taken on line 3-3 of Fig. 2;

Fig. 4 is a sectional view taken on line 4-4 of Fig. 2;

Fig. 5 is a detail elevation showing the inner ends of the propeller blades secured to a hub;

fipeolfication of Letters Patent.

Patented Nov, 19, 1918. Serial No. 225,500.

Fig. 6'is a sectional view of the same;

Fig. 7 is a fragmentary top plan showing a sliding means for tilting the wings at a slight angle, the dotted lines representing the blades in their tilted position;

Fig. 8 is a fragmentary view of the inner portion of the hub; and

Fig. 9 is a fragmentary view showing the operating mechanism for tilting the propeller blades at one side of the air ship.

Referring now to the drawings, it will be seen that my air ship comprises a cigarshaped structure 1, rounded at both ends as at 2 and provided with a covering 3 which is supposed to be water tight, so that the air ship may arise from or alight on either land or water. Formed at the front end of the body portion 1 are the two compartments 4: which are semi-circular in cross-section, the open portion of each compartment being at the opposite side of the said air ship. These compartments may be formed either of wood or metal as desired and extending into each is a propelling shaft 5 which extends along each side of the air ship to similar compartments 6 located. at the rear end of the air ship.

As the forward and rearward propellers on the one shaft are arranged similar to those on the other'shaft, a description of the one shaft, the forward and rearward propellers secured thereto, will be given, and a description of the one set -will therefore be a description of the other.

Mounted on the shaft 5 is a divided hub 6, in which are secured the inner ends of two propeller blades 7. These blades are so formed that their inner ends may turn slightly so that the said blades may not only revolve about the shaft 5 as a central axis, but they may also be slightly tilted with respect to each other from their right-angular position. In other words, these blades 7 are adapted to revolve about a central ax1s 5 and also to tilt or revolve about their own vertical central axes. These blades may be fastened in the divided hub 6 by providing the pins 8 at the inner ends of the propeller blades, which pins are provided with enlarged heads 9 which fit in the divided hub 6.

An outwardly extending stub shaft 10 fastened to the one blade and an inwardly extending stub shaft 11 is fastened to the opposite blade. shafts 10 and 11 are the rods 12 which turn are connected to a sliding collar which is mounted on the operating shaft 5. A movement of this collar 13 therefore will tilt one blade slightly in one direction and the opposite blade in exactly the opposite direction.

The shaft 5 extending from the front compartment to the rearward one is operated by a chain 14 that extends to a centrally located motor 15, and the shaft on the opposite side of the air ship is likewise operated. The rearward propeller blades are also provided with a like sliding collar and connecting bars and the two collars and the four .propeller blades on the one shaft are,to be all operated in unison. Two sets of operating mechanism for moving these collars are to be used, and a description of one set will suffice for the other.

An operating lever '16 is suitably fulcrumed as at 17 and is also loosely connected with an operating bar 18 which is designed to cooperate with both the forward and rearward collars 13 on the shaft 5. A movement therefore of this handle 16 will operate both the forward and rearward set of blades to put them at the angle desired, and the other set of blades on the other shaft as before mentioned is likewise operated.

I have not shown the various controls for the motor, etc, as they may be conventional and form no part of my invention.

The operation of my air ship is therefore as follows: When it is desired to rise directly in the air without any forward motion the propeller blades are set in their normal position as shown in Figs. 2 and 4 and the motor started, which in turn revolves the shafts 5 to which the said propellers are connected. The propellers turning in a downward direction, by reason of the compartments force the airship upwardly and whenit is desired to propel the airship for- I wardly, the two handles 16 are moved,

which in turn operate the sliding collars 13 to. thereby tilt the blades slightly forwardly so that the said blades will be in a propelling angle and thereby force the airship in a forward direction. If desired to remain nearly stationary in the air the blades are again tilted to their normal position and the engine slowed down tosuch a degree that no upward movement will be given to the airship.

When it is desired to turn either to the left or right, one of the levers 16 is forced forwardly and the other rearwardly so that the propellers on one side will act in a forward direction while the ones on the opposite side act in a rearward direction, there by turning the said airship as desired.

From the foregoing it will be seen that the airship is one that may rise horizontally into the air, may be driven forwardly or rearwardly as desired, and may be run at a slow speed either in a. forward or rearward direction.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. An airship having two main propelling shafts extending longitudinally of said air ship and positioned at the opposite sides thereof, two admcent compartments in the forward end' of said airship and two adjacent compartments at the rearward end of said airship and propeller blades secured to the forward and rearward ends of said shafts and located in said compartments, the said blades normally being in the plane of said shafts and to revolve about said shafts as a central axis, and the forward and rearward blades adapted to be moved out of the planes of said shaft.

2. An air ship comprising a motor, two longitudinally extending shafts and means connected with said motor to said shaft to o erate the same, four compartments in said airship located at the opposite ends of said shafts, and propellers fastened at the ends of said shafts and in said compartments, the adjacent blades of each propeller adapted to be tilted with respect to each other, means for tilting all of the blades on one shaft at one time, means for tilting all of the blades on the other shaft at one time, the said blades being normally set in the plane of said shaft.

3. An air ship, a motor therein, two oppositely arranged shafts extending longitudinally of said air ship, compartments semicircular in shape with their open. endstoward the sides of said air ship positioned at both forward and rearwardends, propeller blades secured on the endsof both of said shafts, said blades adapted to be turned about their central vertical axes and sliding collars located on said shafts and connected with said blades for tilting the same, the said blades beingnormally in the plane of said longitudinally extending shafts and to rotate around said shafts as a central axis, the blades on one shaft being operated in unison and the blades on the other shaft also operated in unison.

In testimony whereof I afiix my signature in presence of two witnesses. I ANDREAS MARIUS VAR BEZOOYEN.
